SUPPORTl FOR SPINNING-SPINDLES,

SPECIFICATION forming part of Letters Patent No. 365,417, dated June 28, 1887.

iro al? whom, z' may concern.-

Be it known that I, J osErH WARREN WAT- TLES, of Canton, in the county of Norfolk and Aio Commonwealthv of Massachusetts, have invented certain new and useful Improvements in-Supports for Spinning-Spindles, of which the follow-ing, taken in connection with the accompanying drawings, is a specication.

Spindle supports or bearings of the class to which my invention relates have heretofore A been constructed with the bolster, or the portion in which the spindle revolves, arranged loosely within a bolster-holder, both withA and without a yielding packing interposed between the two, so as to be capable of movement laterally to accommodate itself to the gyrations of the spindle when carrying an unbalanced load, and, these bolsters have in some instances beenprovided with a step for lthe spindle,

forming, when so constructed, a combined b01- ster and step, and in :others they have been constructed independently.thereof. In allforms of bearings of this class,however, as heretofore constructed, not Aonly have the bolsterholders been formed of metal, but also the bolsters, and when a step has 'been formed integrally therewith the stephas been formed of metal as well, so that-in operation the bolster or the step, or both, has or have had metal contact at some point through the holder with the rail. As a result of this, the vibrations and jar in the spindle engendered by its revolution when carrying an unbalanced load have been communicated through metal contacts to the rail, which, being rigid and unyielding,

has not taken them up, but has, on' the other hand, resisted them, causing thereby their augmentation in the spindle, and in consequence vhas occasioned much noise and loss of power.

great measure the objectionable noise caused- A by the rotation of the spindle, has lnot obviated the metal contact between the bolster and its holder, and hence has not neutralized the vibration and j ar incident thereto andl to the rotation of the spindle, and the other, While advantageous when employed lwith the particu-v lar form of spindle used in connection there-v with, is not adapted to that form of spindle in which the step extends below the whirl, and which requires in its operation not only a step, but a bolster as well.

' The object of my invention is tovobviatethc defects above pointed' out and to produce a spindle-bearing which, while adapted to that form of spindle which requires a bolster and step, shall be simple and inexpensive in construction, shall be efficient -in operation, and vwhich shall not be liable toget out of order.

To this end my invention consists in the several combinations of parts, as hereinafter lnore particularly described, and their extent is de- -fined irl the subjoinedelairns. Y

Referring to the drawings, Figurel is a vie\ of a sleeve-whirl spindle and the bearings therefor constructed in accordance with my invention, some of the parts being shown in section; and Fig. 2 is a similar viewof a modiiication of theA same, in which a. projecting sleeve for t-hc combined bolster and step is employed..

In all these figures, A represents the spindle, and B the bolster-holder, both of which are or may be of any suitable or known construction, the forms selected by me for the exempliication of my invention, however, being substantially those illustrated in Letters Patent No. 227,129, and require no det-ail descrip tion herein. i Y

G is a stud or post projecting upwardly from the interior of the bolster-holder B, in the socket or chamber b of which latter it is rigidly secured bya pin, b', and is formed at its upper end,by being bored axially thereimwith a bolster, c, and step c,in and upon which the 4spiudleA rotates and is supported. Thisstud or post, which combines within itself both a bolster and step, is made of wood, rock-maple,dog- Wood, or beach beingV preferred, and is constructed with the portion which enters the socket or chamberv of the bolster-holder of ICC such form as to snugly fit therein, while the portion projecting above such socket or chamber is gradually tapered toward the upper end, which latter is surrounded by a metal ring, ci, to prevent splitting.

The object of making the upper portion of the combined bolster and step tapering is to render it as flexible and yielding as is possible.

I employ wood in the construction of the combined bolster and step, for the reason that experience has demonstrated that spindlebearings when made of such material, not only offer the minimum amount of frictional resistance to the rotation of the spindle and adapt themselves more readily to the varying conditions ofthe latter when carrying an unbalanced load, but, being more yielding and of a softer nature than the surfaces with which they contact, take up the jar engendered by the rotation of the spindle and obviate the jumping of the latter and the disagreeable noise which is experienced when metal is employed.

The form of the interior surfaces of the bol- Ster c and step c will of course be modified to suit them to the particular form of spindle employed, and in order to prevent the swelling of the parts when in operation from the effects of moisture, and with a view to a more perfect bearing-surface for the spindle, the combined bolster and step, after having been properlyy formed, is soaked iu oil until completely saturated therewith. rlhe oil thus taken up will in most instances be sufficient for thepurpose oi lubrication for some months; but to the end that lubricants may be applied whenever desired, I provide the oil-ducts d, which are in communication with the usual reservoir or chamber, f.

In Fig. 1 I have shown the combined bolster and step as extending for some distance above the bolster-holder, and this is the construction preferred; but, if desired, a supporting-tube extending up and around the same to prevent breakage or too great lateral movement thereof, as shown at B in Fig. 2, may be employed.

By the construction above set forth it will be seen that I have produced a bolster and step which is not only simple and inexpensive in construction and effective in operation, but which obviates the metal contacts vbetween such bearings and rail, and thereby removes the various objections incident thereto.

I am aware that a combined bolster and step made from metal and combined with a bolster holder is not new, as the same is shown in Letters Iatent No. 205,718; also, that wooden bearings for spindles have heretofore been used, as illustrated, for instance, in Letters Patent No. 309,903, and I therefore lay no claim to such devices, broadly; but,

Having described my invention and the means employed by me for carrying it into effect, what I claim, and desire to secure by Letters Iatent, is-,

1. The combination, with the sleeve whirl spindle A and bolster-holder B, provided with the oil-reservoirf, of the combined bolster and step formed of wood and rigidly secured in said holder, and the pin b', said combined bolster and step being provided with au oil-duct, d, which communicates with the oil-reservoir,

substantially as described.

2. The combination, with the sleeve-whirl spindle A and bolster-holder B, of the wooden combined bolster and step c, constructed with its upper portion of tapering form, and having its lower end rigidly secured in the said bolster-holder, substantially as described.

3. The combination, with the combined bolster and step c, formed of wood, having the tapering upper portion, as shown, of the metal ring c2, applied to the upper end thereof, substantially as described.
